Description: LR9D01, 02, 08 and 32These self-powered electronic thermal overload relays are designed for direct mounting to contactors LC1D09 through LC1D38. LR9D110S self-powered electronic thermal overload relay is designed for separate mounting only.

In addition to the protection provided by the TeSys D thermal overload relays (see page B11/31), they offer the following additional features:

b protection against phase imbalance b choice of starting class b protection of unbalanced circuits b protection of single-phase circuits
